The main difference between positron emission and electron capture is that, in positron emission, a proton inside the radioactive nucleus is converted into a neutron while releasing a positron whereas, in electron capture, a proton-rich nucleus of a neutral atom absorbs an inner shell electron which then converts a proton into a neutron emitting an electron neutrino. Positron emission and electron capture are two such pathways. Radioactive decay of an unstable isotope of a particular element converts that isotope into a different isotope of a different chemical element. Positron Emission:Positron emission occurs as a conversion of a proton into a neutron, positron and an electron neutrino.Įlectron Capture:Electron capture occurs as a conversion of a proton into a neutron and an electron neutrino by absorbing an inner shell electron. Positron Emission: Positron emission emits a positron along with an electron neutrino.Įlectron Capture:Electron capture emits an electron neutrino and gamma radiation. Positron Emission:Positron emission is a type of radioactive decay in which a proton inside a radioactive nucleus is converted into a neutron while releasing a positron and an electron neutrino.Įlectron Capture:Electron capture is a type of radioactive decay in which the nucleus of an atom absorbs an inner shell electron and converts a proton into a neutron, releasing an electron neutrino and gamma radiation.

Both forms do not change the atomic number or mass number of an atom.ĭifference Between Positron Emission and Electron Capture Definition.

Similarities Between Positron Emission and Electron Capture Carbon-13 is a natural, stable isotope of carbon. It forms a carbon-13 atom along with an electron neutrino and gamma radiation. The above reaction gives the electron capture of a nitrogen isotope. Since the electron capture results in a loss of an electron in the electron shell, it is balanced by the loss of a proton (positive charge), hence the atom remains electrically neutral. However, the mass number does not change. The positron emission takes place in proton-rich radioactive nuclei.Įlectron capture causes the reduction of an atomic number by 1 because the atomic number is the total number of protons in an atomic nucleus, and in this process, a proton undergoes conversion into a neutron. An electron neutrino (Ve) is a subatomic particle that has no net electrical charge. It is also called beta particle (β + or e+). A positron is a subatomic particle with the same mass as an electron and a numerically equal but positive charge. Positron emission is a type of radioactive decay where a proton inside a radioactive nucleus is converted into a neutron while releasing a positron and an electron neutrino. Key Terms: Atom, Electron, Electron Neutrino, Nucleus, Neutron, Positron, Proton, Radioactive Decay What is the Difference Between Positron Emission and Electron Capture What are the Similarities Between Positron Emission and Electron CaptureĤ. This is the main difference between positron emission and electron capture.

In positron emission, a proton inside the radioactive nucleus is converted into a neutron while releasing a positron in electron capture, a proton-rich nucleus of a neutral atom absorbs an inner shell electron which then converts a proton into a neutron, emitting an electron neutrino. Both these processes take place in proton-rich nuclei. Electron capture is a process which emits an electron neutrino. Positron emission is the release of a positron and an electron neutrino in the process of radioactive decay. There are different decay pathways such as positron emission, negatron emission and electron capture. Radioactive decay causes an isotope of a particular element to be converted into an isotope of a different element. Therefore, in order to become stable, these isotopes undergo a spontaneous process called radioactive decay. There are certain naturally occurring isotopes that are unstable due to the imbalanced numbers of protons and neutrons they have in their nucleus of atoms.
